if its not a crate motor try a 400 on the rf and a 175 on the left rear.

where is the lift arm? what shock/spring?

thanks guys for the reply.....5th coil i think is at 34 inchs with a 3comp 8 rebound......350 spring.....
i thought about trying to stiffen rf my self...thought maybe there was too much rear steer.....the track went tacky since i posted this so havent tried it yet.....now the car owner is buying a 2014 4 bar rayburn.......need to know which is better and why......underslung or over rail......

Neither will be better just cause of the bars,under a bit stronger over more room to work.
